IMPROVEMENT m PEGGlNG-MACHINES.

Specification forming part of Letters Patent No. 157,929, dated December22, 1874; application filed June 9, 1874.

To all whom it may concern Be it known that I, EVERETT P. RICHARD- SON,of Lawrence, in the county of Essex and State of Massachusetts, haveinvented an Improvement in Machines for Uniting the Soles and Uppers ofBoots and Shoes; and I do hereby declare that the following, taken inconnection with the drawings which accompany and form part of thisspecification, is a description of my invention sufficient to enablethose skilled in the art to practice it.

The invention has particular reference to that class of machinesorganized to cut from wire nail-forming lengths, and to drive the nailsto unite parts of leather-work--such, for instance, as the soles anduppers of boots and shoes the present improvement relating to the methodof, and mechanism for, presenting the wire to the cutter and nail-tube,and to the construction, arrangement, and method of operating thenail-carrier, by which the nail to be driven is brought under the driverand over the tube or foot, through which the nails are successivelydriven.

In my invention I use, in combination with the vertically-reciprocatingnail-driver, a nailcarrier or wheel at the end of a horizontalrock-shaft turning in suitable bearings, the wheel being in the verticalplane of the naildriver and the nail-tube foot. Through this wheelextend two diametric passages, (preferably crossing at right angles,)there being a suitable stop, by which the wheel, in turning in eitherdirection, is arrested in position to bring one or the other of itsdiametric passages into vertical line with the driver above and the tubeof the foot beneath. Upon one side of this wheel is the wire-cutting ornailforming mechanism, preferably composed of shear-blades,withhorizontal or approximately horizontal cutting-edges. The wire isfed horizontally between these cutters, a nail-length passing betweenthem and entering one of the carrier-tubes, the wheel being turned afterthe nail is cut, and thereby bringing the tube and the nail therein intoupright position, (from horizontal position,) in which upright positionit is in line with the driver and driver-tube, and ready to be driven,the movement that brings it to vertical position carrying the other tubeinto horizontal position, ready to receive the end of the wire to benext severed. After the driving and severing, the wheel is turned back,bringing the emptied tube into horizon; tal line with the cutters, andthe charged tube into vertical line with the driver. Two pairs ofcutters are or may be used, one pair having edges standing at rightangles to the wire, and the edges of the other pair standing at an anglethat will sever the wire, so as to leave on the end of the nail severed,and also on the end of the Wire, an acute-angled point, the othercutters cutting squarely through the wire. Thus one pair of cuttersforms the heads for two adjacent nails, and the other pair the pointsfor two nails; and when the wheel is in position for the severed nail toenter it point first, the wheel is turned so as to leave the nail invertical position point down, the wheel being then in position so thatthe next nail enters it head first, and the wheel being then turned backso that such nail is brought to position with its point down.

The invention consists primarily in the organization and details oforganization thus generally described.

The drawing represents enough of the mechanism of a nailing-machine toenable my invention to be readily understood.

Figure 1 shows the parts in front elevation. Fig. 2 is a side elevationof them. Fig. 3 is a plan. Fig. 4 shows the cutters in end view andplan.

a denotes the frame-work; b, the bearing or guide, through which thestock 0 of the driver reciprocates vertically. Under, or in verticalline with, this driver is the foot-piece 6, through which extends thenail-tube, the work to be nailed being presented against the bottom ofthis foot. Between the driver-stock and nailtube foot is thecarrier-wheel f, the wheel being immediately over the foot 6. This wheelis shown as placed at the end of a shaft, g, turning in a stationarybearing, h, and having two diametric passages, t k, crossing, as beforedescribed, the wheel, by suitable mechanism, being alternately turnedforward and back, to bring each tube in succession under and for theaction of the driver, to drive the nail through the wheel into andthrough the nailtube and into the work beneath.

The nail-supplying mechanism is shown as arranged as follows: lm denotethe horizontal cutter-levers, pivoted at 0 19, carrying at their innerends apair of cutters, the edges of which are horizontal, orapproximately so. The levers being operated by a cam, 'r, thecutting-edges are brought together in the horizontal plane of the centerof the carrier-wheel, the cutters being separated when released by asuitable spring. The wire passes horizontally through guides s, andbetween the cutters into the horizontal passage of the wheel, (being fedforward to the proper distance for the required length of nail,) andwhen thus presented the cutters close upon and sever the nail, leavingit in the carrier-wheel; then the wheel turns and brings the nail intoposition to be driven, as before described. Two pairs of cutters areshown, the edges of one paint a, being respectively shaped like commonwire-nippers, or so as to cut squarely across the wire, leaving the twoends formed by the cut square, or substantially so, the edges of theother cutters being inclined in a horizontal plane, and forming twoinclined points.

The first cutters form the heads for two adjacent nails, as seen at A,and the other cutters the points for two adjacent nails, as seen at B,and each nail is brought to proper position for driving as follows: Thewire having been severed, as seen at B, (the end of the wire beingthrust into the wheel, and the severed ends being pointed,) the wheel isturned so as to bring the nail to vertical position with its pointed enddown, the upper end of the 7 nail being square, and the nail being inproper position to be driven. By this movement of the wheel it isbrought to position to receive the end of the wire to be severed for thenext nail, the square cutters forming the two heads, as seen at A. Thepointed end of the wire is now in advance, and the wheel is turned inthe opposite direction to bring the point of the nail downward. Thus, byalternately turning the wheel in opposite directions, the heads for twoadjacent nails may be formed by one cut, and the points for two adjacentnails by the next out. To bring the respective heading-cutters andpointing-cutters into position at proper times, the cutter-levers aremade movable horizontally, they being pivoted to a block, 0), fixed tothe end of a shaft, w, which slides in its bearing a.

I claim- 1. In combination with the driver and nailtube foot, ahorizontal shaft carrying a nailcarrier, located between the driverstockand foot, the carrier having diametric passages or pockets foralternately receiving the nails and successively presenting them in linewith the driver and the nail-tube foot.

2. The reciprocating nail-carrier on a horizontal shaft, and the cuttingmechanism, relatively arranged and cooperating and combined with thedriving mechanism, substantially as shown and described.

3. The two pairs of cutters for alternately heading and pointing thenails, substantially as described.

4. The process of forming and presenting the nails, consisting insevering the wire to form two heads, and next to form two points, andturning the successive nails in opposite directions from horizontal tovertical position, so as to bring each nail into position to be drivenwith its point downward, substantially as described.
